Gameboy

Summary Courtesy of The Unofficial
Captain N Homepage

King Charles is about to come
home through a warp zone that only opens every 1000 video years. But he decides
to send a supercomputer called Gameboy in his place. Gameboy turns out to be
nothing but trouble for the N Team. Mother Brain gets Gameboy, and Dr. Wily
turns him into Game Brain. When the N Team comes to Metroid to rescue Gameboy,
Game Brain sends monsters after them. Duke comes to the rescue, pulling the
cords out of Gameboy with his teeth! The monsters disappear. Back at the
Palace, the gang officially welcomes Gameboy to the N Team.
